Guild Wars 2

So far I’ve found:

Orb resetting AT the garrison altar mid-siege, before the gates are breached, thus the Lord is invuln. and you can’t flip the garrison before the zerg arrives. Orb then resets at north altar anyway like normal.

Orb disappearing from map and resetting up north after being grabbed at the Bay keep and said player holding it was reported to have jumped in the water. Orb randomly disappearing from the map entirely, despite a player actually confirming they have it.

Alleged “Fly hacking” where an orb left the hills keep, flew straight to garrison keep for another team, and rested there for the evening after being defended for 5 hours straight.

Is there any clarification on the “4 hour reset” for orbs going back up to the altar, please?

Lord not losing invulnerable buff “determined.” at all, and need clarification on exactly what causes the buff to go away, please.

“Broken Altar” not resetting (i.e. At the garrison) and need clarification on what causes it to be “fixed” besides a server reset. Hell…what causes it to “break” anyway?

Lord being invulnerable for extended periods of time (several hours) at defensive garrison allowing us to hold it with impunity (obviously lame).

Any confirmed explanations to this would be awesooooome. Thanks.
